Definitions

  • the invention relates to a process for the treatment of ammonium-containing wastewater in a deammonifying activated sludge plant in which ammonium is first converted to nitrite by means of aerobic oxidizing bacteria (AOB) and then by means of anaerobically oxidizing bacteria (AMOX), in particular by means of Planctomycetes, ammonium and nitrite in elemental nitrogen be converted, which is discharged in the process resulting excess sludge from the basin.
  • AOB aerobic oxidizing bacteria
  • AMOX anaerobically oxidizing bacteria
  • nitrogen elimination is meant the conversion of biologically available nitrogen compounds such as ammonium (NH 4 ), nitrite (NO 2 ) and nitrate (NO 3 ) to elemental nitrogen (N 2 ), which as a harmless end product outgases into the ambient air.
  • NH 4 ammonium
  • NO 2 nitrite
  • NO 3 nitrate
  • N 2 elemental nitrogen
  • ammonium is oxidized by oxygen via the intermediate nitrite to nitrate.
  • the nitrate is reduced in a first reduction step to nitrite and in a second reduction step to nitrogen.
  • the biological nitrification / denitrification has the disadvantage of a high oxygen demand and thus high energy consumption.
  • denitrification consumes organic carbon, which adversely affects the further purification process and the sludge properties.
  • Deammonification is an autotrophic process that does not require organic carbon. This will make the rest of the cleaning process more stable.
  • Deammonification is an efficient method of biological nitrogen elimination, e.g. also with waste water with high ammonium concentrations.
  • AOB aerobic ammonium oxidizing bacteria
  • AMOX anaerobic ammonium oxidizing and elemental nitrogen producing bacteria
  • the aerobic ammonium oxidizing bacteria (AOB) produce 10 times more new bacterial mass relative to the metabolic rate than the anaerobic ammonium oxidizing bacteria (AMOX).
  • the residence time of the sludge in the single-sludge system must therefore be at least as long that the slow-growing anaerobic ammonium oxidizing bacteria (AMOX) can accumulate.
  • AMOX anaerobic ammonium oxidizing bacteria
  • AOB aerobic ammonium oxidizing bacteria
  • a sufficiently high wastewater temperature (> 25 ° C) is the basis for the existence or the growth of the anaerobic ammonium oxidizing bacteria (AMOX).
  • AMOX anaerobic ammonium oxidizing bacteria
  • NOB nitrate-forming bacteria
  • AMOX anaerobic ammonium oxidizing bacteria
  • the invention has for its object to provide an improved and economically feasible method for the treatment of ammonium-containing wastewater available.
  • a method in which the discharged excess sludge into a heavy phase, which contains the majority of the anaerobic ammonium oxidizing bacteria (AMOX), and is separated into a light phase, wherein the heavy phase is returned to the system and / or collected and another plant is fed and the light phase is disposed of.
  • AMOX anaerobic ammonium oxidizing bacteria
  • anaerobic ammonium oxidizing bacteria By disposing of the light phase and returning the heavy phase to the basin, the slow-growing group of anaerobic ammonium oxidizing bacteria (AMOX) can be enriched.
  • the reaction volume of the basin can be reduced accordingly and the process stability of the plant can be increased. Wastewater contaminants, heavier than Planctomycetes, must be separated before the activation plant, otherwise they will also accumulate in the system would.
  • the activation system can be designed as a single-basin system or as a multi-basin system.
  • the temperature of the waste water which influences the existence or the growth of the anaerobic ammonium oxidizing bacteria (AMOX), is no longer of decisive importance by the method according to the invention, so that the deammonification is still effective even with waste water with a temperature of about 10 ° C and can be applied reliably.
  • AMOX anaerobic ammonium oxidizing bacteria
  • the temperature affects all bacteria more or less in the same way (about a doubling of the turnover rate per 10 ° C temperature increase).
  • conventional deammonification in a single-basin system at low temperatures would require such a large tank volume that it would no longer be economical.
  • the retention of the AMOX by the method according to the invention enables an efficient process even at lower temperatures.
  • anaerobic ammonium oxidizing bacteria AMOX
  • NOB nitrate-forming bacteria
  • AMOX anaerobic ammonium oxidizing bacteria
  • the commissioning time of a new plant for the treatment of wastewater by the inventive method can be significantly reduced because the required for a process-safe Deammon Eat proportion of anaerobic ammonium oxidizing bacteria (AMOX) is achieved much faster by supplying a heavy phase from another plant.
  • AMOX process-safe Deammon Enzyme proportion of anaerobic ammonium oxidizing bacteria
  • a particularly advantageous development of the present method is also achieved by carrying out the separation of the excess sludge into a heavy phase and a light phase in a hydrocyclone.
  • a hydrocyclone also called centrifugal separator
  • the excess sludge can be particularly fast and reliable in a heavy phase, which is returned by an underflow of the cyclone in the tank, and a light phase, which is discharged through the upper run of the system, separate.
  • the separation of the excess sludge into a heavy phase and a light phase is carried out in a centrifuge.
  • a centrifuge separates the excess sludge by exploiting the mass inertia. The heavier, higher density sludge fraction migrates outward due to its inertia and displaces the lighter, lower density sludge fraction into the center of the centrifuge.
  • FIG. 1 shows a single-basin plant 1 for the treatment of ammonium-containing wastewater 3.
  • the single-basin plant 1 comprises a basin 2 for receiving the ammonium-containing wastewater 3, an inlet 4, a vent 5 and a drain 6.
  • the ammonium contained in the wastewater 3 is first converted into nitrite by means of aerobic oxidizing bacteria (AOB).
  • AOB aerobic oxidizing bacteria
  • AMOX anaerobic oxidizing bacteria
  • Planctomycetes By means of a pump 7 is formed in the reactions resulting excess shot sludge into a hydrocyclone 8.
  • the excess sludge is separated into a heavy phase containing predominantly the anaerobic ammonium oxidizing bacteria (AMOX) and a light phase.
  • AMOX anaerobic ammonium oxidizing bacteria
  • FIG. 2 shows an activation plant 11 for the treatment of ammonium-containing wastewater 3.
  • the wastewater 3 passes from a primary sedimentation tank 12 via an aeration tank 13, in which the wastewater is vented 3, in a secondary clarifier 14.
  • secondary clarifier 14 of activated sludge from the wastewater 3 is separated by sedimentation and partly recycled as return sludge in the aeration tank 13 or disposed of as excess sludge.
  • a pump 7 By means of a pump 7, a portion of the excess sludge is introduced into a hydrocyclone 8.
  • the excess sludge is separated into a heavy phase containing predominantly the anaerobic ammonium oxidizing bacteria (AMOX) and a light phase.
  • AMOX anaerobic ammonium oxidizing bacteria
